Description

Scope of the utility model

The utility model relates to agricultural engineering.

State of the art

A known screw conveyor for conveying bulk materials, including a cylindrical conveying pipe, a conveying screw arranged therein, connected to the drive, an unloading nozzle and a loading chamber in the form of a cone-shaped funnel covering the lower part of the casing and the open portion of the conveying screw covered by a tape spiral. The direction of the turns of the conveyor screw and the tape spiral do not match. The tape spiral, placed coaxially with the conveyor screw, is cantilevered with its lower end to the hub connected with the drive, freely, freely sitting on the shaft of the transport screw and in the bottom of the loading chamber. The screw and spiral are installed with the possibility of counter rotation (see patent RU 2130418, publ. 05.20.1999).

The disadvantage of this design is the high damageability of the transported material as a result of falling into the gap between the conveying pipe of the loading device and the screw.

The closest technical solution is a device for transporting seeds, consisting of a drive, loading and unloading chambers, a screw with a shaft located in the transport pipe, and the shaft is rigidly connected to the transport pipe in a spiral of blades in a single design (see patent RU 171625 U1 , published on June 7, 2017, Bull. 16).

In this design, the conveying pipe and the loading device are separated, the housing of the loading device is stationary, and the conveying pipe rotates. Moreover, they are located in one plane, which makes the loading process difficult and damage to the transported material is observed.

Utility Model Disclosure

The objective of the proposed utility model is to develop a loading and conveying device assembly, which allows to reduce the material consumption of the structure, reduce energy consumption for the material loading process and reduce its damage.

The technical result that can be achieved using the proposed site loading and conveying device is to reduce damage and reduce energy consumption for the process of loading material into the conveying pipe of the screw container, as well as to reduce the material consumption of the structure.

The technical result is achieved using the node of the loading and conveying device containing the loading hopper, a section of the screw located in the loading hopper, the boot of the loading chamber, the conveying pipe and the blades rigidly connected to it in a spiral.

Reducing damage to the transported bulk material, for example, grain and reducing the energy consumption of the loading process is achieved by the fact that in the proposed design the surface of the casing of the loading hopper is made at an angle not less than the angle of repose of the transported material, and the screw contains sections, one of which is located in the transporting pipe and the other section is conical and placed in the casing of the loading hopper.

When these conditions are met, a horizontal component of force arises, acting on the bulk material and leading to the noted positive effects.

Brief Description of the Drawings

In FIG. presents a diagram of the node loading and conveying device.

Utility Model Implementation

The unit of the loading and conveying device includes a loading hopper 1, a portion of the screw 2 located therein, a casing of the loading hopper 3, the surface of which is made at an angle not less than the angle of repose of the transported material, the conveying pipe 4 with a section of the screw 5 located in the conveying pipe 4 and rigidly connected to it in spirals of the blades, and another section of the screw 2 is made conical and placed in the casing 3 of the loading hopper.

Loading and transporting device operates as follows.

The transported bulk material, for example, grain enters through the feed hopper 1 to a portion of the screw 2 located in the boot hopper casing 3. The transported bulk material rolls down by gravity along the inclined casing of the feed hopper 3, made at an angle not less than the angle of repose of the transported bulk material. This reduces energy consumption in the organization of the movement of the material by the blades of the part of the screw 2 of a conical shape. Then the material enters the conveying pipe 4 and, under the action of the blades located in the conveying pipe and rigidly connected to it in a spiral fashion, moves on to section 5.

Claims (1)

The node of the loading and conveying device, including the loading hopper and auger, characterized in that the surface of the casing of the loading hopper is made at an angle not less than the angle of repose of the transported material, and the screw contains sections, one of which is located in the conveying pipe, and the other section is conical and placed in the casing of the loading hopper.
